Chrysanthemum plant named &#39;Zanmuday&#39;

ABSTRACT

A  chrysanthemum  plant named ‘Zanmuday’ characterized by its medium sized blooms with yellow ray florets and prolific branching; natural season flowering date October 8 (week 41); blooming for a period of 5 weeks.

BOTANICAL DESIGNATION

Chrysanthemum×morifolium Ramat.

CULTIVAR DENOMINATION

‘Zanmuday’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofchrysanthemum plant, botanically known as Chrysanthemum×morifoliumRamat., commercially known as a garden mum, and hereinafter referred toby the cultivar denomination ‘Zanmuday’. ‘Zanmuday’ is a product of abreeding and selection program for outdoor pot mums (garden mums) whichhad the objective of creating new cultivars with a double typeinflorescence, a natural season flowering date around October 8 (week41), blooming for a period of 5 weeks. ‘Zanmuday’ is a seedlingresulting from a cross of the female parent id 24636 with the maleparent id 26443. Plants of the new cultivar ‘Zanmuday’ differ fromplants of the female parent in inflorescence size; the inflorescences ofthe seedling are larger than those of the female parent. Plants of thenew cultivar ‘Zanmuday’ differ from plants of the male parent innatural-season flowering date; plants of the seedling flower in anearlier period than those of the male parent.

The new and distinct cultivar was discovered and selected as a floweringplant by Wilhelmus Bernardus Blom on a cultivated field in Rijsenhout,The Netherlands in 2007. The first act of asexual production of‘Zanmuday’ was accomplished when vegetative cuttings from the initialselection in 2007 were propagated further in a controlled environment inRijsenhout, The Netherlands. The new cultivar has been found to retainits distinctive characteristics through successive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum isshown in the accompanying drawings, the color being as nearly true aspossible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown outdoor in Rijsenhout, The Netherlands under natural day length andtemperature and planted in week 23 in 2005. The natural blooming date ofthis crop was October 8 (week 41) . The average height of the plants was35 cm. No growth retardants were used. No tests were done on disease orinsect resistance or susceptibility. No tests were done on cold ordrought tolerance. This new variety produces medium sized blooms withyellow ray florets blooming for a period of 5 weeks.

From the cultivars known to inventor the most similar existing cultivarin comparison to ‘Zanmuday’ are ‘Zanmugoldru’ (U.S. Plant Pat. No.20,422) and ‘Zanmugolmine’ (U.S. Plant Pat. No. 22,618). When‘Zanmuday’, ‘Zanmugoldu’ and ‘Zanmugolmine’ are being compared thefollowing differences are noticed: (1) Plant vigor. And (2) Naturalseason flowering date. (1) Plants of ‘Zanmuday’ are slightly lessvigorous than those of ‘Zanmugoldru’, and more vigorous than those of‘Zanmugolmine. (2) Plants of ‘Zanmuday’ and of ‘Zanmugoldru’ flowerlater in the season than those of ‘Zanmugolmine’.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmuday’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society Colour Chart,edition 2001.
